The purpose of this study is to investigate flow pattern around mosquito's wing while it is beating. We constructed an experimental apparatus to simulate the beating motion of mosquito. An enlarged scale model experiment was carried out using a very low speed wind tunnel under the condition that Reynolds number and Strouhal number were made equal to those of real mosquito. The flow field around the wing model moving up and down was visualized using smoke and laser light sheet and it was analyzed by a PIV system. Unsteady vortices were observed to be generated on the upper surface of the model wing in the period of downstrdke. We compared the vortices each other on three different kinds of enlarged scale models (8, 10, 12.5 times). As a result, the flow fields around the wings were almost same regardless of the enlargement scale at the same Reynplds number and Strouhal number condition of symmetrical wing model.
